Vulnerability Name:

CVE-2022-0485 (CCN-235010)

Assigned:2022-01-27
Published:2022-01-27
Updated:2022-12-01
Summary:A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
